How is PPMS diagnosed? I had a small attack 2 years ago. Numbness, temor, bladder issues. All resolved. MRI negative for a year. Stopped doing MRIs and in the past year, I've had stiffness in muscles and I can't walk up stairs. My feet are on fire. Numbness that goes and comes and I have a hard time with my left foot because it feels heavy to walk on. The more I walk I want to favour it more. I am 48 years old . Could I have PPMS?
PPMS is diagnosed on the basis of slow but steady worsening of neurological function consistent with multifocal demyelination of the central nervous system with MRI abnormalities and CSF abnormalities. You can not have relapses; therefore, you can not have PPMS based on your description.
